Abstract
The magnetic properties of the following intermetallic compounds were determined: HFCo2, HfCo3, Hf6Co23, HfCo7, TaCo2, TaCo3, NbCo2, and NbCo3. Several amorphous alloys of the type Y1−xCox (in the concentration range x=0.30 to x=0.55) were prepared by melt spinning. Their magnetic properties have been compared with those of vapor-quenched alloys studied previously. The concentration dependence of the magnetic moments was studied in the following vapor-quenched amorphous alloys: Mg1−xNix, Hf1−xCox, and Nb1−xCox. In various binary systems the magnetic properties of crystalline and amorphous materials have been compared and their differences are explained in terms of a local environment model.
